My research interests lie in the domain of high performance microprocessor
design, but with a low power twist. Initially, power was not a primary concern
in the high performance processor market except for high performance portable
computers. For these products, power was reduced by using a lower voltage
supply and or slower clock frequencies. Unfortunately, this also resulted in a
Recently, though, power dissipation is becoming a dominant concern for the high
performance market primarily because of reliability issues. The next
generation high-end processors will dissipate 50+ Watts of power. This in turn
requires an expensive package to handle the heat. If the package is not
available due to cost limitations, the performance of the chip is throttled
using various mechanisms. Hence power and performance are heavily intertwined,
and reducing the power of the system can have a positive impact on the overall
performance of the processor. My work focuses on micro-architectural redesign to
retain performance while reducing power.
When I have time for fun, I enjoy hiking, biking, skiing, volleyball,
and generally anything that involves the outdoors. I also enjoy
exotic and spicy foods and decadent desserts.
My goal after receiving my PhD is to find an academic position or a position in
a industrial lab where I can still stay active in the research community. My
future research goals are to continue the work on Low Power Systems and high
performance processors with an emphasis on peak power dissipation and its
impact on processor reliability. Besides Low Power Microprocessor design, I
would like to expand into the areas of system level power issues and power and
performance tradeoffs in application specific processors, such as Graphics and
